摘要
本文基于Lyapunov稳定性理论,采用非线性反馈控制方法,设计出了两个Liu系统的同结构同步,以及Liu系统与统一混沌系统的异结构同步的控制器,给出了实现同步的充分条件以及控制参数的适用范围。理论证明和数值仿真表明,所给方法能使系统误差很快的收敛到零,快速实现同步,显示了方法的有效性。
In this paper,according to Lyapunov stability theory,nonlinear feedback control method is employed to work out isostructure synchronization of two Liu systems and controller of diverse structure synchronization between Liu system and unified chaotic system,obtain the sufficient condition for realize synchronization and the range of controller ＇s parameter.Theoretical proof and numerical simulation demonstrate the effectiveness of the proposed method which making the system error quickly converges to zero and rapidly realize synchronization.it shows the effectiveness of the method.
